"So when they got evicted (not sure of the reasoning) they had to do a complete pull of everything in the apartment. It has been about a year and the apartment has not been even touched."
They had to do a complete pull of everything in the apartment. Okay this means? And it has been about a year and the apartment has not been touched, so did they or did they not have someone come in clean out and detoxify the apartment? I gather no, so the apartment has just been sitting there for a year.
And now, lets see, your ten year old is acting up. Is anyone else having any health problems? But you're taking care of this problem, you're moving out. And breaking the lease. Want to know if there's a point in seeing an attorney to what, sue them for not cleaning the apartment next door properly? Allow you to break the lease without penalty because they haven't cleaned up the apartment properly? Or sue the apartment complex for something that you believe to be making your ten year old ill or causing them psychological problems? I'm not really understanding.
It doesn't sound as though there is any conclusive proof that you have yet, and you are now in the process of moving out, that would show that you or family members would be suffering from any long term lasting health issues right now from rumored meth cooking in the apartment last year. It's hard to say there will be issues in the future.
In fact, the meth cooking thing is dying down, thank the Lord! And around my part of the world, it really helped that Sudafed is harder to get now. Too bad for all the legitimate users of Sudafed, having seen the meth crisis first hand far too much around here, I do not care if they make it harder to get antihistamines. Legitimate wanters can get them still. Just don't smurf in and try to buy fifteen packs.
That, combined with the fact that the stupid folks who do a lot of meth have mostly od' ed and killed themselves by now, with black tar heroin and fentalyl laced crap everywhere that is easier and safer to buy than it ever was to cook the meth (and cooking it took some small degree of math and measurement skills) means it's dying out.
One thing I have noticed is that the meth house pollution crisis that was so big several years ago....well, nobody seems to be dying on the streets now because they were exposed to the very vehement very identifiable scent of meth cooking a year or two ago. I think you might want to talk to an attorney, but frankly, I suspect you'll end up paying to break the lease anyway. You don't even know for sure if there was any meth cooking activity next door and it would take a while and a lawsuit to find all that now.
